Broadhead blade gravity lock and inertia release apparatus and method

Abstract

A broadhead blade gravity lock and inertia release apparatus and method consists of a. support structure with a locking pin channel. A blade is attached with the support structure such that the blade is movable from a first position to a second position. A pressure device is connected with the blade where the pressure device is configured to apply pressure to the blade. A locking pin is located in the locking pin channel where the locking pin is free to move toward and away from the blade within the locking pin channel and where the locking pin is configured to releasably connect with the blade such that when the blade is connected with the locking pin the blade is held in the first position by the pressure on the blade and where compressive force on the blade releases the blade from the locking pin such that the pressure device then pressures the blade to the second position and where, when connection with the blade is removed, the locking pin is free to move away from the blade within the locking pin channel.

What is claimed is: 
     
       1. A broadhead blade gravity lock and inertia release apparatus comprising:

 d. a locking pin in said locking pin channel wherein the locking pin is free to move toward and away from said blade within said locking pin channel and wherein said locking pin is configured to releasably connect with said blade such that when the blade is connected with the locking pin said blade is held in the first position by the pressure on the blade and wherein compressive force on the blade releases the blade from the locking pin such that the pressure device then pressures the blade to the second position and wherein when connection with the blade is removed said locking pin is free to move away from said blade within the locking pin channel. 
 
     
     
       2. The apparatus of  claim 1  wherein said locking pin channel is configured to enable movement of the locking pin such that gravity causes said locking pin to move toward said blade when said support structure is held in one position. 
     
     
       3. The apparatus of  claim 2  wherein said locking pin is located in front of said blade within said support structure such that gravity causes said locking pin to move toward said blade when said support structure is held vertically. 
     
     
       4. The apparatus of  claim 1  wherein said locking pin channel is configured to enable movement of the locking pin such that inertia causes said locking pin to move within said locking pin channel away from said blade when said blade is released from connection with the locking pin upon compression of said blade upon impact of the support structure with an object. 
     
     
       5. The apparatus of  claim 1  wherein said locking pin includes a locking lip and wherein said blade includes a locking lip connector configured to releasably connect said blade with said locking pin. 
     
     
       6. The apparatus of  claim 5  wherein the blade includes a length with a first end and a second end and a locking pin connector wherein the locking pin connector is configured to connect the blade in the first position with the locking pin in the locking position. 
     
     
       7. The apparatus of  claim 6  wherein the locking pin connector is a receiver slot in the blade and the locking pin lip is configured to fit within the receiver slot such that the blade is retained in the first position. 
     
     
       8. The apparatus of  claim 7  wherein the receiver slot includes a first edge and a second edge wherein the second edge extends past the first edge such that the second edge pushes away the locking pin in the locking pin channel as the blade moves toward the support structure. 
     
     
       9. The apparatus of  claim 1  further including more than one blade. 
     
     
       10. A broadhead blade gravity lock and inertia release apparatus comprising:
 a. a support structure with a locking pin channel; 
 b. two blades attached one opposite from the other with the support structure such that each blade is movable from a first position to a second position; 
 c. a pressure device connected with said two blades wherein said pressure device is configured to apply pressure to said two blades; and 
 d. a locking pin in said locking pin channel wherein the locking pin is free to move toward and away from said two blades within said locking pin channel and wherein said locking pin is configured to releasably connect with said two blades such that when the two blades are connected with the locking pin said two blades arc held in the first position by the pressure on the two blades and wherein compressive force on the two blades releases the two blades from the locking pin such that the pressure device then pressures the two blades to the second position and wherein, when connection with the two blades is removed, said locking pin is free to move away from said two blades within the locking pin channel. 
 
     
     
       11. The apparatus of  claim 10  wherein said locking pin channel is configured to enable movement of the locking pin such that gravity causes said locking pin to move toward said two blades when said support structure is held in one position. 
     
     
       12. The apparatus of  claim 11  wherein said locking pin is located in front of said two blades within said support structure such that gravity causes said locking pin to move toward said two blades when said support structure is held vertically. 
     
     
       13. The apparatus of  claim 10  wherein said locking pin channel is configured to enable movement of the locking pin such that inertia causes said locking pin to move within said locking pin channel away from said two blades when, upon compression of said two blades upon impact with an object, said two blades are released from connection with said locking pin. 
     
     
       14. The apparatus of  claim 10  wherein said locking pin includes a locking lip and wherein said two blades include a locking lip connector configured to releasably connect said two blades with said locking pin. 
     
     
       15. The apparatus of  claim 14  wherein the two blades include a length with a first end and a second end and a locking pin connector wherein the locking pin connector is configured to connect the two blades in the first position with the locking pin in the locking position. 
     
     
       16. The apparatus of  claim 15  wherein the locking pin connector is a receiver slot in the two blades and the locking pin lip is configured to fit within the receiver slot such that the two blades are retained in the first position. 
     
     
       17. The apparatus of  claim 16  wherein the receiver slot includes a first edge and a second edge wherein the second edge extends past the first edge such that the second edge pushes away the locking pin in the locking pin channel as the two blades move toward the support structure. 
     
     
       18. A broadhead blade gravity lock and inertia release method consisting of:
